TRICONEX 3381工業(yè)卡件
工程卡僅當選擇通道卡時，工程卡按鈕功能才會運行。參見第3.3節(jié)。如果工程卡上沒有安裝工程鑰匙，以下工程卡按鈕將不可用：抑制零量程第一量程。如果按下這些按鈕中的任何一個，則所選通道卡信息顯示屏上將短暫顯示鎖定符號（）。4.2超時當操作未安裝工程鑰匙的工程卡時，超時時間為30秒。如果在超時時間內(nèi)沒有按下按鈕，將自動取消選擇所選通道卡。4.3條形圖顯示當操作未安裝工程鍵的工程卡時，所選通道的條形圖顯示將繼續(xù)顯示可用工程卡功能運行期間的實際氣體讀數(shù)。4.4催化傳感器電橋電流與BEAD mA按鈕相關(guān)的操作僅適用于催化通道卡。使用所選其他類型的通道卡操作此按鈕無效，并且短時間顯示警告消息（XXXX）。要進入催化傳感器電橋電流操作，請按以下步驟進行：（1）按住所需的通道卡RESET/SELECT（重置/選擇）按鈕約1.5秒，直到所選圖標出現(xiàn)在通道顯示器上。（2） 按下BEAD mA按鈕，所選通道卡顯示屏將指示配置的電橋電流。例如200mA。（3） 按下拒絕（）按鈕或等待30秒以退出胎圈mA模式。
查看報警級別設(shè)置
報警按鈕的操作允許查看每個報警設(shè)定點A1、A2和A3的報警閾值點和報警類型（上升或下降）。要進入報警視圖操作，請按以下步驟進行：（1）按住所需通道卡RESET/SELECT（重置）/SELECT（選擇）按鈕約1.5秒，直到所選圖標出現(xiàn)在通道顯示器上。（2） 按下ALARMS（警報）按鈕，所選通道卡顯示屏將顯示A1級警報，如相反所示。注：向上箭頭A表示上升報警，向下箭頭A表示下降報警。（3） 再次按下報警按鈕，所選通道卡顯示屏將指示A2級報警。（4） 第三次按下ALARMS（警報）按鈕，所選通道卡顯示屏將指示A3級警報。（5） 第四次按下ALARMS（警報）按鈕，所選通道卡顯示屏將指示STEL液位警報。（6） 第五次按下ALARMS（警報）按鈕，所選通道卡顯示屏將指示LTEL級別警報。（7） 進一步按下報警按鈕將再次滾動報警水平設(shè)定點。即A1、A2、A3、STEL和LTEL。注：當報警功能被禁用時，報警閾值將在數(shù)字顯示屏上顯示為“---”。（8） 按下（）或（）按鈕或等待30秒以退出報警模式。
ENGINEERING CARD
The Engineering Card push-button functions will only operate if a channel card is selected. See Section 3.3. Without the Engineering Key fitted to the Engineering Card, the following Engineering Card push-buttons will not be available: Inhibit Zero Span 1st Span If any of these push-buttons are pushed, a locked symbol ( ) will be briefly displayed on the selected channel card message display. 4.2 Timeout When operating the Engineering Card without an Engineering Key fitted there is a timeout period of 30 seconds. If no push-buttons are pressed within the timeout period, the selected channel card will automatically be deselected. 4.3 Bar Graph Display When operating the Engineering Card without an Engineering Key fitted, the selected channel's bar graph display will continue to indicate the actual gas reading during the operation of the available Engineering Card functions. 4.4 Catalytic Sensor Bridge Current The operation associated with the BEAD mA push-button only applies to catalytic channel cards. Operating this push-button with other types of channel cards selected has no effect and the warning message (XXXX) is displayed for a short time. To enter the catalytic sensor bridge current operation, proceed as follows: (1) Push and hold the required channel card RESET/SELECT pushbutton for approximately 1.5 seconds until the selected icon appears on the channel display.(2) Push the BEAD mA push-button and the selected channel card display will indicate the configured bridge current. eg. 200mA. (3) Push the reject ( ) push-button or wait 30 seconds to exit the Bead mA mode.
View Alarm Level Settings
The operation of the ALARMS push-button allows the viewing of the alarm threshold point and alarm type (rising or falling) for each alarm set point A1, A2 and A3. To enter the alarm view operation, proceed as follows: (1) Push and hold the required channel card RESET/ SELECT push-button for approximately 1.5 seconds until the selected icon appears on the channel display. (2) Push the ALARMS push-button and the selected channel card display will indicate the A1 level alarm as indicated opposite. Note: The up arrow A indicates a rising alarm while the down A arrow indicates a falling alarm. (3) Push the ALARMS push-button a second time and the selected channel card display will indicate the A2 level alarm. (4) Push the ALARMS push-button a third time and the selected channel card display will indicate the A3 level alarm. (5) Push the ALARMS push-button a fourth time and the selected channel card display will indicate the STEL level alarm. (6) Push the ALARMS push-button a fifth time and the selected channel card display will indicate the LTEL level alarm. (7) Further pushes of the ALARMS push-button will scroll through the alarm level set points again. ie. A1, A2, A3, STEL and LTEL. Note: Where an alarm function is disabled, the alarm threshold value will be displayed as '- - - -' in the digital display. (8) Push the ( ) or ( ) push-buttons or wait 30 seconds to exit the ALARMS mode.
